Today’s lesson... What: Comparing And ORDERING RATIONAL NUMBERS Why: To compare and order groups of fractions, decimals, percentages.

Comparing and Ordering Fractions, Decimals, and %’s STRATEGY #1: Convert everything into ____________ first! STRATEGY #2: Start with the __________ #’s, move onto the tenths, etc. decimals whole

When comparing decimal #’s... Start with the __________________________ place value digit and compare. If there is a “tie,” move on to the next digit, etc. In other words... 1) Compare the whole numbers. 2)If there is a “tie,” move on to the ______________________________. 3)If there is another “tie,” move on to the _______________________________. 4)If needed, keep moving on to the next place value digit(s). greatest tenths hundredths

Remember: CONVERT TO DECIMALS FIRST!!!!
